WTB 16mm collets for cutter grinder

[WestVinTools]

This might be a longshot....
I bought a cutter grinder from a retired tool and die maker this week. It came with one collet and now I'd like to find a set or at least a few sizes.
It's a 16mm shaft diameter deckel/Alexander collet (not the 20mm diameter collets).
If anyone is interested in selling them please let me know. Nothing is on eBay right now and they're kinda scare to find. But it's a beautiful cutter grinder after I cleaned it up.

Nice find!

I wonder if these are the collets you would need? Company is in Europe.

I'm not sure if these are the correct size but some guys were retrofitting Deckel's with these knock-offs. I cant speak to accuracy.

Initially most of the Taiwan/Chinese Deckel copies were using the original U collets. Some still do but some are slowly drifting to R8 because more available & popular collet in N-Am.
But you might find U sets with places like Shars, Grizzly, maybe Accusize like below machine. For a while they were offering both versions.

BTW, lots of experienced machinists using the Asian T&CG wheels. If you havent seen Stefan Gotteswinter or Rob Renzetti YouTubes, both have covered their Deckel clones in detail.
You made a nice score there, looks forward to some pics when its up & running.

Unfortunately those items won't fit but thank you for having a look for me. PeterT, I've seen those videos before. Gotteswinter needs to post a new video lol. I need to find the video where he retrofitted his to take his Deckel collets. I almost wonder if it would be worth it to have a machine shop make a set. There's room to invest in a set of collets as the grinder cost me $100. There are plenty of 20mm diameter shaft ones out there, but I haven't seen 16mm yet. I attached a PDF of the collet from another forum where someone had the same challenge.

@WestVinTools : instead of a collet, is there any thought to having the collet base perhaps but reworking the head of the collet as say an ER collet holder? looking through the web seems to be a lot of folks searching for collets for that machine.

 

[WestVinTools]

@Brent H , yes I've thought about that as well and may go that route.
I'd like to know the manufacturer of the cutter/grinder. I have looked online but have yet to see one with a grinding wheel on the opposite end of the cup wheel and it looks like it came from the factory like that. It's extremely well built.

Again, I might be off base, but if they are Lorch collets I believe those were more widely used in jeweler lathes. Looks like there were different sizes within that name though. I've seen the same issue come up when people acquire those lathes with missing or incomplete collet sets, so I bet they are out there. You might have to buy the whole lathe to get the collets haha.

What brand of cutter grinder is this? This looks to be a cross between the Deckle SO and a bench grinder.

 

[WestVinTools]

@MGordon I wish I knew what brand. I haven't yet seen a picture of it on internet searches.

I just picked up a little Alexander cutter grinder that also takes the 16mm collets. I'm wondering how difficult it would be to make some, rough turn and toolpost grinder for the finish?
